You can manually add/remove items using the methods "catalog_object" and "uncatalog_object" (Zope Book and google for more info). hth Jonathan (another one) ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

[Zope] ZCatalog question
Hi Folks, i have a ZCatalog over a bunch of items with attributes A and B. Now I want to search all elements with attribute A set to value 1 and AT THE SAME TIME with attribute B set to value 2. So a sort of AND combination with two different attributes. How to do ? Regards oliver --- "All language designers are arrogant. Goes with the territory..."

Sorry, the patch I posted yesterday was not complete.
There have been too more problems:
* if the wildcard expansion could not find matching words,
my patch created an empty subquery.
Such queries, unfortunately, can not be handled by
"UnTextIndex.evaluate".
The new patch, instead creates a new search term,
'no_expansion_for_'. Hopefully, this term is not
indexed and thus gives the same results as
the empty subquery.
Of cause, this is a hack.
The ZCatalog maintainer should find a better solution.
* The ZCatalog, more precisely, "UnTextIndex.__getitem__"
still raises an "IndexError" exception, when one searches
for a term that is not indexed.
The result is "no data matches your query", even for
an "or" query.
I had already put a patch for this error in the collector
for Zope 2.2.1, but apparently, DC decided not to
look at it.
Please discard my patch from yesterday.
You may give the new patch (appended) a try.

[Zope] ZCatalog question. boolean and wildcards.
Im running Zope 2.2.2 on Linux 2.2.13. When mixing boolean operators and wildcards '*' in queries within a Textindex the 'AND' operator is replaced by 'OR'. Also, the possibility of constructing nested terms using brackets seems to be not supported (contrary to the chapter 'Searching and indexing' from the Zope book). The setting is straightforward, several indexes (text-index, keyword-indexes) are used indexing a about 5000 Zclasses. Are there any patches to apply or what else can i do ? Thanks in advance.

[Zope] ZCatalog Question
I have a product that has three CatalogAware Zclasses. They are indexed by the catalog correctly, but when I look at the catalog's status tab, the number of objects for each index are identical, even though the ZClasses themselves don't all have the same properties. Intuitively, this seems wrong. Or maybe my intuition is wrong. It "makes more sense" to have differing number of objects based on how many of each type of ZClass instance was indexed and what the properties of each one was. Anyone have any enlightenment (or is that Zen...) ?
